"It is serious and has really heated up," a source tells Us of the new couple. Another source adds, "It's a fun relationship for both of them. She's just about as busy as he is and it's not really feasible [for them] to become a more committed couple, but the hang outs are great."

The pair were spotted on a romantic date in Brooklyn, N.Y.'s Prospect Park and Botanical Gardens on Friday, May 29. They got cozy together under a tree and took photos of one another around the grounds.
